As patient\u2010based and multi\u2010dimensional clinical evaluation tools, these systems should be capable of reflecting the walking disability of patients. The association between JOA<\/jats:styled-content> scores and gait parameters, however, are not well characterized. The purpose of this study was to determine the correlations between JOA<\/jats:styled-content> scores and gait parameters of patients with cervical spondylotic myelopathy (CSM<\/jats:styled-content>) and lumbar intervertebral disc herniation (LDH<\/jats:styled-content>).<\/jats:p><\/jats:sec>Methods<\/jats:title>A total of 32 CSM<\/jats:styled-content> and 30 LDH<\/jats:styled-content> patients with gait dysfunction were recruited for the present study. All patients were diagnosed by two senior orthopaedic doctors and evaluated with JOA<\/jats:styled-content> scoring systems. A body\u2010mounted motion analyzer, the I<\/jats:styled-content>ntelligent D<\/jats:styled-content>evice for E<\/jats:styled-content>nergy E<\/jats:styled-content>xpenditure and A<\/jats:styled-content>ctivity (IDEEA<\/jats:styled-content>), was applied to measure gait parameters of patients across 30\u2009m of flat floor in an orthopaedic ward. A linear regression model was used to determine the correlations between JOA<\/jats:styled-content> scores and gait parameters. Multiple linear regressions were used to identify the relationships between subsections of the JOA<\/jats:styled-content> systems and gait parameters.<\/jats:p><\/jats:sec>Results<\/jats:title>Japanese O<\/jats:styled-content>rthopaedic A<\/jats:styled-content>ssociation scores of LDH<\/jats:styled-content> patients from the JOA<\/jats:styled-content> lumbar scoring system are significantly correlated with gait speed (R<\/jats:italic>\n2<\/jats:sup> = 0.557, P<\/jats:italic> < 0.001) and stride length (R<\/jats:italic>\n2<\/jats:sup> = 0.544, P<\/jats:italic> < 0.001). JOA<\/jats:styled-content> scores are also correlated with double support duration, step duration, cycle duration and cadence, and weakly correlated with single support duration. For the four subsections of the JOA<\/jats:styled-content> lumbar scoring system, \u201crestriction of activities of daily living\u201d is the significant predictor of all gait parameters, especially gait speed (R<\/jats:italic>\n2<\/jats:sup> = 0.573, P<\/jats:italic> < 0.001) and stride length (R<\/jats:italic>\n2<\/jats:sup> = 0.553, P<\/jats:italic> < 0.001). However, JOA<\/jats:styled-content> scores of CSM<\/jats:styled-content> patients from the JOA<\/jats:styled-content> cervical scoring system are only weakly correlated with these measures (all R<\/jats:italic>\n2<\/jats:sup> < 0.3). For the four subsections of the JOA<\/jats:styled-content> cervical scoring system, \u201cmotor function of the lower extremity\u201d is a weak predictor of gait parameters (all R<\/jats:italic>\n2<\/jats:sup> < 0.3).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>There is a significant correlation between gait parameters and functional disability as measured by the JOA<\/jats:styled-content> lumbar scoring system, which indicates that the JOA<\/jats:styled-content> lumbar scoring system can reflect gait impairment. The JOA<\/jats:styled-content> cervical scoring system, however, may need to be improved for efficiently evaluating the walking ability of CSM<\/jats:styled-content> patients in the assessment of motor function of the lower extremity.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.12280","type":"journal-article","created":{"date-parts":[[2016,12,29]],"date-time":"2016-12-29T12:40:27Z","timestamp":1483015227000},"page":"447-453","source":"Crossref","is-referenced-by-count":19,"title":["Correlations of J<\/scp>apanese Orthopaedic Association Scoring Systems with Gait Parameters in Patients with Degenerative Spinal Diseases"],"prefix":"10.1111","volume":"8","author":[{"given":"Chen\u2010fan","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Biomechanics and Rehabilitation Engineering, School of Biomedical Engineering, and Beijing Key Laboratory of Fundamental Research on Biomechanics in Clinical Application Capital Medical University Beijing China"},{"name":"Rehabilitation Engineering Research Department, Suzhou Institute of Biomedical Engineering and Technology Chinese Academy of Sciences Suzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan\u2010cheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery Tianjin Hospital Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong\u2010cheng","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery Tianjin Hospital Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qun","family":"Xia","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery Tianjin Hospital Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Miao","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery Tianjin Hospital Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji\u2010dong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery Tianjin Hospital Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Biomechanics and Rehabilitation Engineering, School of Biomedical Engineering, and Beijing Key Laboratory of Fundamental Research on Biomechanics in Clinical Application Capital Medical University Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,12,29]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"117","article-title":"Deep\u2010wound and organ\u2010space infection after surgery for degenerative spine disease: an analysis from 2006 to 2012","volume":"2016","author":"Garza\u2010Ramos R","journal-title":"Neurol Res"},{"key":"e_1_2_7_3_1","first-page":"133","article-title":"Imaging of degenerative spine disease\u2010\u2010the state of the art","volume":"21","author":"Sasiadek MJ","year":"2012","journal-title":"Adv Clin Exp Med"},{"key":"e_1_2_7_4_1","doi-asserted-by":"crossref","first-page":"487","DOI":"10.1016\/S0030-5898(20)31760-0","article-title":"Cervical spondylotic myelopathy.
